It is because of this property that oxalic acid is one of the primary components in commercial solutions used to remove scale from automobile radiators. [5]

Rust, which is primarily composed of iron oxides (Fe 2 O 3), also reacts with weak acids to form soluble iron salts. The reaction can be simplified as: Fe 2 O 3 + 6H + → 2Fe + 3 + 3H 2 O. In this process, iron ions (Fe + 3) are produced along with water, making the rust easier to remove without causing damage to the underlying metal or ...
